I am using this Samsing SCX 3201g. I have installed Samsung Unified Drivers from Samsung's Site.
It is doesn't have Any Option for Duplex printing. Using same Printer on Windows 7 supports Duplex Printing.
Long Edge Short Edge Settings.
How do i configure these to work in Ubuntu 12.10 if my Printer supports it?
I had the same problem on Samsung SCX 6322 DN Series and this was sorted by installing the driver from the manufacturer.
I'd love to see a fix for this. I'm having the exact same problem with my networked Epson Workforce 630 printer.
I've seen people recommend editing the settings via
localhost:631/printers/
in a web browser, but my printer doesn't have the relevant duplex printing options there either.
There's also printer-config-system. (System Settings -> Printing).
I know it's not my printer that is the problem. It's an excellent all-in-one printer that works great in Windows7.
